Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to a knife adjustment mechanism and a point-breaking folding machine. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. For example, polypropylene pellets are often used as raw materials, and are produced in a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding.

[0003] In the prior art, it is necessary to process non-woven fabrics for point breaking and slitting operations. The point breaking operation on non-woven fabrics mainly involves intermittent cutting of the non-woven fabrics so that the non-woven fabrics can be easily torn and used. When performing the point breaking operation in the prior art, most of them are implemented by point breaking rollers and point breaking knives. However, there are many types of non-woven fabrics, and the thickness and angle of the non-woven fabrics that need to be point broken. The point breaking mechanism in the prior art has the disadvantage of being inconvenient to adjust when point breaking non-woven fabrics of different specifications. Utility Model Content

[0004] The utility model aims to provide a tool adjustment mechanism and point breaking and folding, which can solve the technical problem of the inconvenience of adjustment of the point breaking mechanism in the prior art when point breaking non-woven fabrics of different specifications.
